Waterproof concrete adhesive G70

G70 additive is used in the amount of 5 to 10% by weight of cement.To bond two layers of concrete, one unit of adhesive is mixed with one unit of water.The exact amount of adhesive varies according to the granulation, the amount of surface penetration and the water used. It is the best estimate of workshop experiments.

Sealant Concrete Adhesive G70 : Emulsion polymer for bonding fresh concrete to old and making impermeable mortar

Description :

G70  is a concentrated and homogeneous polymer emulsion based on vinyl acetate resins and is used to increase the adhesion of mortar or to stick a new layer of concrete on the old layer, repair the previous layer and seal structures. Due to the reaction with water and cement, in addition to creating adhesion, it causes cohesion and cohesion in the concrete texture. G70 dissolves after mixing with water but becomes insoluble and impermeable after drying.

Physical and chemical properties:

physical state:                   Concentrated emulsion

Color:                                  Milky

Density:                              1.01 g/cm³

Chloride Content:            No (BS 5075)

Properties and effects:

  • Increase the strength of adhesion and connection between new and old concrete
  • Increase the adhesion and cohesion of mortar components
  • Increase the wear coefficient of concrete
  • Increased resistance to cracking
  • Increasing the strength of concrete in glacial cycles

Application :

  • Repair of chrome concrete and surface damage of concrete structures
  • Gluing components of restorative mortars
  • Possibility of applying thin layers of concrete
  • Connecting new concrete with old concrete
  • Making sealing mortar

Complies with standards:

ASTM C1042 – ASTM C1059 – ASTM C 1440

Consumption :

G70 additive is used in the amount of 5 to 10% by weight of cement.To bond two layers of concrete, one unit of adhesive is mixed with one unit of water.The exact amount of adhesive varies according to the granulation, the amount of surface penetration and the water used. It is the best estimate of workshop experiments.

Method of Use :

Before using G70, the damaged concrete surface should be cleaned of any loose elements, dust and grease and then thoroughly watered with fresh water. There are two ways to use this product.

1- As a concrete adhesive slurry: First, mix the calculated amount of adhesive (20%) with water (15%) and cement (65%) and make a homogeneous slurry. Then slurry to a thickness of 1 to 2 mm on the surface.

2- As a repair mortar: Mix 10 to 40% with dry materials instead of water and make a homogeneous mortar. Irrigate the old concrete surface with fresh water and then (without running water on the old concrete surface) impregnate a layer of adhesive to adhere the new mortar to the desired surface and then apply the mortar on the concrete surface.

Maintenance  :

It can be stored in the original packaging and in a covered warehouse away from direct sunlight at a temperature of 10-40 ° C for one year after the date of manufacture.

Package type :

Packages of 1, 4, 10 and 20 kg

safety tips :

This substance is not flammable and is not harmful to the environment. Avoid contact of this substance with eyes and skin. In case of contact with eyes, rinse immediately with plenty of water. Goggles and gloves are recommended when working.
